| titleOfInvention | A kind of preparation method and application of hyperbranched polyamide modified activated carbon |
| abstract | The invention provides a preparation method of hyperbranched polyamide modified activated carbon. The activated carbon is boiled with deionized water, rinsed, and then vacuum-dried to obtain pretreated activated carbon AC; the pretreated activated carbon AC is added to an acid solution, and the temperature is 60 ℃. React at ~70°C for 6~8h, filter, wash, and vacuum dry to obtain acidified activated carbon AC-H; add acidified activated carbon AC-H to the hyperbranched polyamide aqueous solution, stir and disperse evenly, and then add a shrunk N,N-di Cyclohexylcarbodiimide is reacted at 70~80℃ for 4~6h, washed and dried in vacuum to obtain hyperbranched polyamide modified activated carbon. The hyperbranched polyamide modified activated carbon is used to purify formaldehyde in the air. It combines the two functions of physical adsorption and chemical decomposition. It has very good enrichment and decomposition effects on formaldehyde, can efficiently remove formaldehyde in the air, and avoid It reduces the risk of secondary pollution and can effectively solve the problem of indoor formaldehyde pollution. |
